Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated substations, specifically an emergency door opening device for prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a box-type substation or prefabricated substation, is a compact substation that integrates high-voltage switchgear, transformers, and low-voltage switchgear into a single enclosed enclosure. It typically consists of the enclosure, a high-voltage compartment, a transformer compartment, and a low-voltage compartment. The enclosure offers excellent protection and can adapt to various outdoor environments. The high-voltage compartment connects to the high-voltage power supply and is equipped with high-voltage switchgear, such as circuit breakers and disconnectors, for controlling and protecting the high-voltage circuits. The transformer compartment houses the power transformer, converting high-voltage energy into low-voltage energy suitable for user applications. The low-voltage compartment contains low-voltage switchgear, metering devices, and reactive power compensation devices, responsible for distributing, metering, and compensating for low-voltage energy. By integrating multiple electrical devices into a single enclosure, prefabricated substations significantly reduce the floor space required compared to traditional substations. They are widely used in urban power grid upgrades, industrial parks, residential communities, schools, hospitals, shopping malls, and other locations, providing reliable power supply to various users. In remote areas or temporary power supply locations, prefabricated substations are also widely used due to their flexibility and convenience.

[0003] Existing prefabricated substations have the following shortcomings: They lack emergency door opening functions. During emergency repairs, staff have to manually open the doors by approaching the enclosure. However, this can lead to electrical leakage inside the enclosure, and the powerful current can cause fatal injuries instantly. In addition, the high temperatures caused by equipment failures can also pose a risk of burns to staff, greatly increasing the probability of safety accidents. This not only threatens the lives of staff but also further delays repairs, expands the scope of power outages, and has a serious negative impact on social production and life, resulting in a significant decline in the public's quality of life and social operational efficiency.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution:

[0025] An emergency door opening device for a prefabricated substation includes a box body 1. An insulating plate 2 is fixedly connected to one side of the box body 1. An insulating rod 3 and a storage component are respectively arranged on one side of the insulating plate 2. A locking component is arranged on one side of the box body 1. A pair of connecting blocks 4 are fixedly connected to one side of the box body 1. A rotating block 5 is rotatably connected between the pair of connecting blocks 4. A box door 6 is fixedly connected to one side of the rotating block 5. A handle 7 is fixedly connected to one side of the box door 6. The storage component can store the insulating rod 3 on one side of the insulating plate 2, preventing the insulating rod 3 from being lost or damaged due to random placement. When the insulating rod 3 needs to be used in an emergency, it can be quickly taken out from the storage component, greatly saving the time of finding tools. The locking component can lock the box door 6 through the handle 7. In an emergency, the locking component can be opened first by using one end of the insulating rod 3, so that the handle 7 is released. Then, the handle 7 can be pulled open by hooking the insulating rod 3. The box door 6 is opened by rotating the rotating block 5 between the pair of connecting blocks 4, avoiding direct contact with the box door 6 and greatly reducing the safety risks such as electric shock.

[0026] The storage assembly includes a support base 8 and a pair of elastic plates 9. The support base 8 and the pair of elastic plates 9 are both fixedly connected to one side of the insulating plate 2. A rotating base 10 is rotatably connected to the support base 8. The rotating base 10 has a storage hole that is adapted to the insulating rod 3. A clamping block 11 is fixedly connected to the side of the pair of elastic plates 9 away from the insulating plate 2. The insulating rod 3 is inserted into the storage hole on the rotating base 10. The pair of clamping blocks 11 clamp and fix the insulating rod 3. When the insulating rod 3 needs to be taken out, the insulating rod 3 is pulled. The insulating rod 3 drives the rotating base 10 to rotate on the support base 8. At the same time, the insulating rod 3 squeezes the clamping block 11, the elastic plate 9 deforms, and the insulating rod 3 can be separated from the pair of clamping blocks 11. The insulating rod 3 can be pulled out from the storage hole on the rotating base 10.

[0027] The locking assembly includes a protective cover 12, which is fixedly connected to one side of the housing 1. A pressing rod 13 and a pair of limiting rods 14 are slidably connected to the protective cover 12. One end of the pressing rod 13 is fixedly connected to a limiting plate 15, and one end of each pair of limiting rods 14 is fixedly connected to the limiting plate 15. A spring 16 is fitted around the outer periphery of each limiting rod 14. A telescopic rod 17 is fixedly connected to one side of the limiting plate 15, and a spring 28 is fitted around the outer periphery of the telescopic rod 17. One end of the telescopic rod 17 is fixedly connected to a limiting disc 19, and a button 20 is fixedly connected to one side of the limiting disc 19. A through hole is provided on one side of the protective cover 12, which is compatible with the button 20. A pair of locking holes are provided on the handle 7, each of which is compatible with a limiting rod 14. Both spring 16 and spring 28 are in a compressed state, and the limiting rods 14 are inserted... Insert the corresponding locking hole on the handle 7, press the button 20 with one end of the insulating rod 3, so that the button 20 slides into the interior of the protective cover 12 along the through hole on one side of the protective cover 12. The button 20 drives the limiting disc 19 to push the telescopic rod 17, the telescopic rod 17 retracts, and at the same time the second spring 18 is further compressed. When the button 20 is disengaged from the through hole on one side of the protective cover 12, the first spring 16 can push the limiting plate 15, so that the side of the limiting plate 15 away from the limiting rod 14 is pressed against the protective cover 12. The limiting rod 14, the pressing rod 13 and the telescopic rod 17 all move together with the limiting plate 15. The limiting rod 14 is pulled out from the corresponding locking hole on the handle 7, the pressing rod 13 slides on the protective cover 12, and the telescopic rod 17 drives the second spring 18, the limiting disc 19 and the button 20 to move together. The button 20 slides against the inner wall of the protective cover 12.

[0028] A hook 21 is fixedly connected to the insulating rod 3. Use the hook 21 on the insulating rod 3 to hook the handle 7.

[0029] The outer periphery of the insulating rod 3 is covered with an anti-slip sleeve 22. The anti-slip sleeve 22 can significantly improve the safety and convenience of operation. In emergency repair scenarios, staff are often under high tension and their hands are prone to sweating. The anti-slip sleeve 22 can increase the friction between the hand and the insulating rod 3, preventing the insulating rod 3 from falling off due to slipping hands, and ensuring that the insulating rod 3 can be accurately and stably operated to open the box door 6 during operation.

[0030] The top of the enclosure 1 is equipped with a top cover, which can effectively block rainwater, dust and other impurities, prevent them from entering the enclosure and corroding electrical equipment, reduce the probability of short circuits and failures, and at the same time protect the equipment from direct sunlight, reduce aging and wear caused by high temperature and ultraviolet rays, and extend the service life of the equipment.

[0031] The working principle of this utility model is as follows:

[0032] The insulating rod 3 is inserted into the storage hole on the rotating seat 10. A pair of clamping blocks 11 hold and fix the insulating rod 3 in place. The insulating rod 3 is stored on one side of the insulating plate 2 to prevent it from being lost or damaged due to random placement. When the insulating rod 3 is needed in an emergency, pull the insulating rod 3. The insulating rod 3 will drive the rotating seat 10 to rotate on the support seat 8. At the same time, the insulating rod 3 will squeeze the clamping blocks 11, and the elastic sheet 9 will deform. The insulating rod 3 can be separated from the pair of clamping blocks 11 and pulled out from the storage hole on the rotating seat 10, which greatly saves the time of finding tools.

[0033] Then, press button 20 with one end of insulating rod 3, so that button 20 slides into the interior of protective cover 12 through hole on one side of protective cover 12. Button 20 drives limiting disc 19 to push telescopic rod 17. Telescopic rod 17 retracts, and spring 2 18 is further compressed. When button 20 is removed from the through hole on one side of protective cover 12, spring 1 16 can push limiting plate 15, so that the side of limiting plate 15 away from limiting rod 14 is in close contact with protective cover 12. Limiting rod 14, pressing rod 13 and telescopic rod 17 all move together with limiting plate 15. Limiting rod 14 is pulled out from the corresponding locking hole on handle 7, so that handle 7 is released. Pressing rod 13 slides on protective cover 12. Telescopic rod 17 drives spring 2 18, limiting disc 19 and button 20 to move together. Button 20 slides in close contact with the inner wall of protective cover 12.

[0034] Next, use the hook 21 on the insulating rod 3 to hook the handle 7, and pull open the box door 6 through the insulating rod 3. The box door 6 is opened by rotating the rotating block 5 between a pair of connecting blocks 4, avoiding direct contact with the box door 6 and greatly reducing the safety risks such as electric shock. The anti-slip sleeve 22 on the insulating rod 3 can significantly improve the safety and convenience of operation. In emergency repair scenarios, the staff are often under high tension and their hands are prone to sweating. The anti-slip sleeve 22 can increase the friction between the hand and the insulating rod 3, preventing the insulating rod 3 from falling off due to slipping, and ensuring that the insulating rod 3 can be accurately and stably operated to open the box door 6 during operation.

[0035] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
